Hi Clean, Hi Hygiene! How To Keep Your Air Ducts Clean!
Hi Domestic HVAC Focus!
Part 1:
View below the main key "4 Reasons You Should Clean Your Building’s Air Ducts", we told you that, in general, the EPA doesn’t recommend cleaning air ducts regularly because the agency isn't sure about the benefits of routine cleaning.
Click on any term of EPA on this post or the logo below to visit the United States Environmental Protection Agency to obtain in depth analysis & further information including downloadable .pdf format documentation explaining further the duties on weather if you should have your ducts cleaned at home?
Studies have not shown conclusively that duct cleaning prevents health problems or that particle levels within a building increase because of dirty air ducts.
Air ducts are just one potential source of particles since pollutants can come from outdoors as well as other indoor sources.
However, the EPA does recommend cleaning air ducts if there is visible mold growth, a rodent/insect infestation, if the ducts are clogged with dust/debris, or if it’s obvious that particles are being released into the air through the building’s registers.
There is chance, though, that particles can contaminate your HVAC system due to dirty ducts, or moisture can get in the system, causing mold to grow and potentially releasing mold spores into the air.
That’s why it’s in a facility manager’s best interest to take whatever preventive measures he can to keep the ducts clean.
Here’s what the EPA suggests to keep dirt from entering the system:
- Change filters regularly, and change them more often if they become clogged.
- Use the highest efficiency air filter as recommended by the HVAC system manufacturer.
- Make sure you don’t have any missing filters, and make sure air cannot bypass the filters through gaps around the filter holder.
- When servicing the HVAC system, clean cooling coils and drain pans.
- When undergoing any type of construction that produces dust, seal off the registers and do not operate the HVAC system until after the dust is cleaned up.
- Vacuum the facility regularly preferably with a HEPA vacuum, and clean dust from surfaces regularly.
- If the facility’s heating system has an in-duct humidifier, operate and maintain the humidifier as specified by the manufacturer.
To prevent ducts from getting wet:
- Repair leaks and water damage immediately and correctly.
- Inspect cooling coils regularly. Cooling coils are designed to remove water from the air and can be major sources of moisture contamination, which can lead to mold growth.
- Check that the condensate pan drains properly as the presence of a substantial amount of standing water or debris indicates a problem. Also check that there are no wet spots on the insulation near the cooling coils.
- Ducts should be properly sealed and insulated in spaces that aren’t air conditioned like attics. This prevents moisture from condensation from entering the system.
- Select an air conditioning system for your facility that is sized correctly, and seal all the ducts at the joints.
If your facility does have a situation that warrants duct cleaning, duct cleaning equipment cleans ducts quickly and easily.
Duct cleaning equipment can clean 4″-18″ round and spiral ducts and 4″-16″ rectangular/square ducts in a simple one-person operation.
*Some of the features that can be available with duct cleaners include; flexible shafts, rotary brushes, reversible shaft rotation, adjustable speed control and a three-stage true HEPA filtration system.

reasons why you should clean your buildings
air duct's;
If your HVAC system is not properly installed or maintained, dust, pollen and other debris particles can contaminate it. If moisture gets into the system, mold can grow and mold spores may be released from the system into the air.
The end result is that your building’s occupants may experience allergic reactions or other symptoms related to poor indoor air quality (IAQ).
You've probably seen the advertisements for duct cleaning, which means cleaning all the components of your HVAC system, including the ducts, the drips pans, and the coils.
If you listen to the claims of the duct cleaning companies, it would seem facility managers should place duct cleaning at the top of their maintenance lists.
But, in general, the EPA doesn’t recommend cleaning air ducts that regularly because the agency isn't sure about the benefits of routine cleaning.
Studies haven’t proven that duct cleaning prevents health problems or that particle levels in buildings increase due to dirty air ducts. Air ducts are only one of the possible sources of particles, as pollutants can come from the outdoors or from indoor sources such as cleaning and cooking.
However, even the EPA, says air ducts should be cleaned in these cases:
- If there is visible mold growth on the ducts or on other components of the HVAC system
- If the ducts are infested with rodents, insects or other vermin
- If the ducts are clogged with dust and debris
- If particles are obviously being released into the building from the registers
In the event, that your facility does require duct cleaning, duct cleaning equipment cleans ducts quickly and easily.
We repeatedly inform as previously mentioned above the duct cleaning equipment can clean 4″-18″ round and spiral ducts and 4″-16″ rectangular/square ducts with a simple one-person operation.
Again some of the features available with our duct cleaners include flexible shafts, rotary brushes, reversible shaft rotation, adjustable speed control and 3-stage true HEPA filtration system.
If you decide to hire a company for duct cleaning, it’s important to make sure the technicians clean all the system components.
Not cleaning every component can cause the system to become re contaminated by any remaining particles, according to consulting firm Building Air Quality (BAC).
